ahh..I guess I was thinking the fuel was filtered past the tank but before it hit the pump.
nope, after the pump mr. honeywell
you have a surprisingly diverse signature, sir.
as long as nothing smaller then 10 microns is between the
the filter outlet on the fass pump, anything that wears off the pump, if it is after the filter, (which it probably isn't) and your fuel injector then it is ok .
but that is a lot of pipe , hose , and a few connections from the middle of the truck , to the heads. Maybe some how purging the lines right before the last hook up would help some .
maybe i am just paranoid ...
not paranoid - just not familiar with the system
take a look at how it's set up when it's together, feed goes to water separator, up to pump, down from pump to filter, then out.
have you ever taken one apart? i just swapped pumps, so i can verify this for you. dennis @ ITP was also talking about this in another thread
the hose routing is not particularly overwhelming - you have the suction tube to the FASS (couple feet), then the return from the FASS to the filler neck (couple feet) and then the feed to the motor (i used 10'). it's pretty simple.
69W is right - you could even run a line from the FASS to the stock feed hardline after the pump, and then ditch the fuel bowl and just make some (3) feed connections - don't need the RR since the FASS is regulated.
